build,test: make building addon tests less fragile by bnoordhuis · Pull Request #17407 · nodejs/node

bnoordhuis · 2017-11-30T23:42:35Z

get rid of recursive make for building the node binary
use module name 'binding' in addons.md and addons-napi/*/binding.gyp
make addons-verify.js write out dependencies for generated add-ons
make gyp write out dependencies for all static deps

This is prep work for a dusted off and super-powered version of #12231.

make finally works as intended now:

$ make
make: Nothing to be done for 'all'.

And make -j8 test (finally!) builds add-ons in parallel.

Awesome, I'll get that CI stuff working post-haste

make finally works as intended now:

Can you elaborate? Is the point that if nothing has changed it doesn't still do a load of stuff?

tools/gyp/pylib/gyp/generator/make.py

Should we float the gyp changes in a separate commit in case we lose them in a future gyp update?

Good idea. I'll split it out before landing.

Can you elaborate? Is the point that if nothing has changed it doesn't still do a load of stuff?

Yep. Right now it always does this:

Makefile

cc @nodejs/build in case there are any jobs directly running the build-ci target.

richardlau · 2017-12-02T00:54:39Z

Makefile

Does $(ALL_DEPS) include out/Makefile? Since this target recursively executes make it should have a dependency on the makefile.

joyeecheung · 2017-12-03T13:15:55Z

Makefile

For some reason the CI is complaining

+ make run-ci -j 2 make -C out BUILDTYPE=Release V=1 make[1]: *** out: No such file or directory. Stop. Makefile:91: *** Missing or stale config.gypi, please run ./configure. Stop. Build step 'Execute shell' marked build as failure

BridgeAR · 2017-12-11T05:52:11Z

Ping @bnoordhuis

This seems pretty nice but since the Makefile is a place where things change often, I hope we can get this done fast and land it.

bnoordhuis · 2017-12-11T11:10:51Z

@BridgeAR IIRC, it needs some CI tweaks and @gibfahn was going to look at that.

gibfahn · 2017-12-11T12:14:12Z

@BridgeAR IIRC, it needs some CI tweaks and @gibfahn was going to look at that.

I don't recall saying I was going to look at this. I'm happy to, but the CI we were talking about was a build with cmake.

CI fails as this needs a rebase. https://ci.nodejs.org/job/node-test-commit/14743/console

bnoordhuis · 2017-12-15T21:43:51Z

Rebased and I decided to check in the documentation add-ons. They don't change often enough to go through the trouble of generating them dynamically. Too race-y, too special.

~~https://ci.nodejs.org/job/node-test-commit/14876/ - mostly green except for an inscrutable AIX issue.~~

bnoordhuis · 2017-12-16T22:07:22Z

Glorious green! Please (re)review. The biggest change from the previous changeset:

Check in auto-generated add-on tests from doc/api/addons.md. The
files change rarely and generating them dynamically causes no end of
race conditions and special-casing during the build.

richardlau · 2017-12-17T00:27:11Z

Makefile

Is config.gypi intentionally dropped here?

Yes, but it's no longer necessary. I've pushed up a commit that restores it.

I take back what I wrote - it's still necessary because of the config.gypi: configure rule below. But since it's correct to depend on config.gypi here, I'll just remove the other rule.

gibfahn · 2017-12-17T12:28:11Z

doc/api/addons.md

Is there a way we could validate this? Maybe a test that contains the shasum of everything inside a js code block in this file, that you have to update when it changes.

I guess tools/doc/addon-verify.js would be the place to do it.

I've added a commit that adds a --check flag to addon-verify.js and calls that from make test.

Makefile

This should be marked as phony.

richardlau · 2017-12-19T16:21:51Z

With the config.gypi rule removed, we now get this which is probably less helpful for newcomers:

-bash-4.2$ git clean -fdX
-bash-4.2$ make
make: *** No rule to make target `config.gypi', needed by `out/Makefile'.  Stop.
-bash-4.2$

Is there a reason the makefile doesn't just run configure to generate config.gypi? In most cases it should yield sensible defaults(?).

bnoordhuis · 2017-12-19T16:25:14Z

Is there a reason the makefile doesn't just run configure to generate config.gypi?

It used to and it was supremely annoying because it overwrote your settings. I removed it a few years ago.

edit: to expand on that, you'd get situations like these:

$ ./configure --prefix=/path/to/dir
# edit some files, time passes
$ make -j8 install
# runs configure again but without --prefix and installs to the wrong location

gibfahn · 2017-12-19T16:44:34Z

Is there a reason we can't have the config.gypi rule with these changes? I'm a fan of the more helpful error message.

How about only generating a new config.gypi if there isn't one there already?
